In the interest of transparency, An Garda Síochána publishes figures on their website on roads policing offences by Garda Division. This includes a divisional breakdown of incidents where a vehicle was detained under Section 41 of the Roads Traffic Act 1994 from a driver without an approved insurance policy.
This can be found at the following link:www.garda.ie/en/roads-policing/statistics/roads%20policing%20offences%20by%20region%20and%20division/.
The collation of data on cases before the courts is a function of the Courts Service.
To be of assistance, I have referred your question to the Courts Service for their direct reply. The Courts Service has a dedicated email address for the provision of information to members of the Houses of the Oireachtas: oireachtasenquiries@courts.ie.
